Origin of Azad Kashmir bauxite

Bauxite and the associated rocks from seven different localities in Muzaffarabad and Kotli areas of Azad Kashmir have been investigated for their clay and non-clay mineral composition. Rocks in contact with the bauxite are the fire clay at the base and Eocene shale at the top. The fire clay overlies the precipitation breccia of Permo-Carboniferous age. No relationship could be established between the precipitation breccia and the bottom of the overlying fire clay. The undulatory contact between the fire clay and the bottom of the bauxite which grades upward into highly pisolitic variety indicates their common parentage in alkaline igneous and metamorphic rocks exposed to the north and north-east of Muzaffarabad Trough. The environment and cycle of deposition of the bauxite and the fire clay were also similar with some break and changes when the pisolites of the bauxites were being formed
